In a device 'ofthis characterit is desirable to provide automatic means'for placing the cups or containers upon the conveyer and,

this is accomplishedby nesting the cups, one

within another, and depositing thecups one atvatime' from the'bottom" of the nest or stack to and u on the conveyer beneath';'.andthisis accomp ishedby the following meeh anism. I provide a supporting-bracket46," which isv supported on legs" 46A.' The bracket 46-is adjustable relative'to the frame 1, by means .of the slots 53 in'the legs 46A' being slidable upon thethreaded bolts 54,"
